There is a roll pin right below the dust cover on right side of my SP10. I marked it in the picture below. Any idea why it’s there? Thanks

Thank you. How would you remove it if you wanted to? Tap it through? I guess it’s just a stop used when installing the pivot pin so it really never gets removed?
 
Ok. I can’t feel the back side of a pin when I stick my finger up inside the mag well. I thought I was seeing a pin but perhaps just the aluminum hole? I just didn’t know why the hole was there. Watching the video of installing and removing the front pivot pin, the guy never makes reference to the hole or if there is a pin inside the hole. The lower he has also shows a hole there. Maybe it’s a drain hole like you said?
 
Thread about it on m4carbine.net.

Well it looks like the hole is deliberate and could be useful for manufacture and maintenance. I‘m glad I’m not the only one who has wondered why it was there.
